Hi, its never known at runtime what the path will be. You mentioned though 'using this approach'. Could you let me know some other approaches I could use if this one does not help me?

If everything else fails you can P/invoke LoadLibrary and then try to call the functions in the DLL somehow. I think I saw an article here somewhere doing just this, but I could be wrong.
Good luck,

I don't think it's possible to do it dynamically using .NET.
What you could do is make an unmanaged DLL that works as a stub, which is always the same. Then you link to that stub DLL from your .NET code. That DLL determines the path of the DLL to load, and uses LoadLibrary and GetProcAddress to link to it.

I have an array declared like this:
byte[,] grayPixels = new byte[rows, cols];
later in the code, (where I don't have access to rows or cols), I have to iterate through grayPixels, I am using the following code to find the number of rows
int nRows = grayPixels.Length;
How can I find out the number of columns in the above array? Thanks in advance...

Use grayPixels.GetLength(0) to get the size of the first dimension, and grayPixels.GetLength(1) to get the size of the second dimension.

Hello
int nRows = grayPixels.GetLength(0);
int nCols = grayPixels.GetLength(1);

Hi Greeky,
Well the easy way is to set the AcceptsReturn property of the textbox to true. That should let them press enter onto new lines.
If you want to do it manually, just change the code to the following (converted to c# from interesting vb hybrid)
<br />
protected void txtAddress_KeyUp(........) {<br />
if(e.key == keys.enter)<br />
{<br />
txtaddress.Text += environment.newline;<br />
txtaddress.SelectionStart = txtaddress.Text.Length-1;<br />
txtaddress.SelectionLength = 0;<br />
}<br />
}<br />
<br />
The two lines to note are setting SelectionStart and SelectionLength. This just says move the cursor to the last character, and make sure no text is selected.
Hope this helps
Philip

If I write a DLL assembly in C# using .NET, can I use it in my VC++ / MFC projects? My question is can such C# DLL be used in C++ type projects WITHOUT first converting the DLL in a COM ?
Thanks

Just set your C# project to Register For COM Interop in Project Properties.

is there any way within the .net framework to determine if a string contains a numeric value?
|
|
|
|
|
The easiest way is to put a try...catch around the conversion:
try {
num = int.Parse(str);
ok = true;
} catch {
ok = false;
}
Exceptions are quite expensive, though, so it's more efficient to validate the string before you convert it. You can use the Regex class to check if the string only contains digits, for an example.
---
b { font-weight: normal; }

do you mean if the string is a number, or can contain a number somewhere amongst a lot of other characters?
For the first, if you want to figure out if a string is a number, I'd use Double.TryParse(string) to figure this out (returns a boolean). (Much more effective then "try-catch"ing)
For the latter, I'd use regular expression to match any digits (\d) and then it'll return boolean. (regular expression can also subtract the numbers it finds, if needs be...)
I hope this help.

i have windows service program,and i want to make a config file for it.
if the config file is placed in the directory:system32/,i can access it by System.Environment.SystemDirectory,but when placed in the windows service executable files' directory(bin\debug\),i don't know how to access it.
|

You don't need to access the file directly.
Use the classes in the system.configuration namespace to access the configuration file.
If you just have simple string data to access then you can use the AppSettings class and section.
Otherwise you can write your own section handler.
The file should be named yourexe.exe.config, but vs.net will copy any file named app.config from the root of your project to the output directory and rename it to the proper name so your service will read it.
